As far as I know that should work. Is the VM crashing maybe? What
happens above after the domain creation, does the console just sit there
after 'Escape character is ^]' or does it exit immediately? If it exits,
something went wrong.

When you say you are unable to connect using virsh console, do you mean
it doesn't print anything or the command fails? If it fails, please post
the output.
